Toadl whom, it may concern:

Be it known that I, Janna J. Anuson, a citizen of the United States,residing at Rockfalls, in the county of Whiteside and State of Illinois,have invented certain new and useful Ini rovements in Stoppers forBottles; and I i o declare the following to be a full, clear, and exactdescri ation of the invention, such as will enable ot ers skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention has reference to siphon-bottle stoppers, and is speciallydesigned to he used in connection with bottles containing Carbonatedwaters, mineral waters, and similar liquids wherein a pressure isexerted from the inside of the bottle to expel the contents thereof.

My device is simple and durable and so constructed as to permit of theuse of one discharge-pipe interchangeably with different bottles, doingaway with the necessity of having a discharge-pipe attached to eachbottle, as is now the case. It is also possible to fill or refillbottles provided with my invention by the use of any usual means, nospecial apparatus being required therefor, as is the case with manybottles now in use.

In the drawin 's, Figure 1 is a central vertical section of abottlefitted with my device. Fig. 2 shows the discharge-pipe used inconnection therewith. Fig. 3 is an enlarged detail showing the stopperin vertical section with the dischar 'e-pipc in position therein. Fig. 4is a detail s owin the lower end of the plug 4. Fig. 5 is an enlargeddetail, in vertical section, showing a modified form of the d ischarge-p i pe.

Similar numbers refer to similar parts throughout the several fi ures.

1 represents the bottle, and 2 a hollow stopper, in the lower end ofwhich is tightly fixer a siphonipe 3, extending nearly to the bottom ofthe ottle. The stop or 2 is preferably formed of rubber and the pipe 3of glass. In the upper part of the stopper 2 is tightly seated a plug 4,also of rubber and having a vertical perforation 5, in which is fixed ametal sleeve 6. At the lower end of the plu 4 is a three-wayincision 7,formin a nprmally closed valve in the lower end of 51s p u".

'fhe bottle may be provided with a. cap 8 or other suitable cover, suchcovering being provided with a perforation 9 centrally thereof in linewith the perforation 5.

10 is a discharge ipe having at one end a tube 1 l adapted to e insertedin the sleeve 6 and to force 0 )01'1 the valve in the lower end of theplug 4. he operation is aided by means of a button 12, fixed on thedischarge-pipe at the u iper end of the tube. lipon the o ioning 0 thevalve the liquid in the butt 0 is forced up through the lips 3 and outthrough the dischar *e-pipe. Vlhen a desired amount of the liquii hasbeen released, the dischargeipe is withdrawn and the valve again closes.

y reason of the elasticity of the lower end of the plug 4 there is anatural tendency of the valve to close, and this tendency is aided bythe pressure of the ascs within the bottle upwardly against such valve.By constructing the pipe 10 with a greater diameter than the tube 11 aconsiderable amount of expansion is permitted to the gases before theyreach the mouth of the pipe, and the force of the stream proceedingtherefrom is greatly rcdueed.

In Fig. 5 is shown a construction wherein the pipe 10 is replaced by ashort straighl -upon the button 12.!

It will be seen that the discharge-pipe serves the purpose of a key tounlock the bottie and release the contents thereof and that such pipecan be used in common with all bottles fitted with my device. One ofsuch pipes can be furnished with each case of cnronated goods, or astore-keeper dealing in such oods would only require a limited number ofthe discharge-pipes.

The sleeve 6 is not an essential part of the device, but merely servesthe purpose of keeping the perforation 5 open for the insertion of thetube.

The bottle when fitted with my invention is susceptible of beingrefilled when empty by inserting in the plug 4 a ipe or tube leadingfrom the chargin -cham er and forcing the valve open with the end ofsuch pipe. The plu 4 1S closely embraced by the stopper 2, sue stopperexerting a contractile force upon the ower art of the lug and aiding inkeepin the va ve in the ower end thereof norma y closed.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-

1 'A stopper for bottles of the class named comprisin a hollow plug,adapted to be held in the neo of the bottle, and provided at its innerend with aninwardly-o eningvalve; and means for conducting the 11 uidcontents of the bottle from the bottom t ereof to the inner end of saidplug; substantially as set forth.

2. In a device of the class named, a hollow flexible plug, provided inits inner end with an inwardly-o ening valve; a hollow sto per,supported in t e neck of the bottle, an embracing the lower part of theplug; and means for conducting the contents of the bottle to the innerend of said plug; substantially as Y and for the purpose set forth.

3. In a bottle-sto per, the combination of the sto per 2, fixed 1n theneck of the bottle; the hol ow plug 4, embraced by the stopper 2,

sage for the contents of the having an inwardly-opening valve in itsinner end, and rovided with the sleeve 6 centrally of such p ug and thepipe 3 providin a pashottle to t e plug 4; substantially as shown andset forth.

4. In a device of the class named, the combination of the sto per 2,fixed in the neck of the bottle; the hollow plug 4, embraced by thestopper 2, having an inwardly-opening valve in its inner end; the cap 8,fixed on the top of the bottle, and provided with an opening 9, in linewith the openin in the plug 4; and the pipe 3, extendin om the lower endof the stop er 2 to the ottom of the bottle; substantially as shown anddescribed.

In testimony whereof I afiix my signature in presence of two witnesses.
